🛠️ Group Updates

  • Ongoing focus: Information accessibility and collection
    • Information accessibility: How to better structure information, such as the "faq" and the meeting notes for both members and external readers?
    • Information collection: How do we make it easier to contribute and encourage better editing, is this needed? How to best surface pages/examples?
    • Debate about whether to use github for WG notes
    • David, Chris, Balazs, Juan and Snorre to meet for a tooling meeting 19th Aug to discuss and painpoints related to documentation efforts and WG info presentation (open to all membership).
  • Business models and self-sovereignty problems (report-out from IIW mini-conference)
    • Win-win-win solutions and multi-sided marketplaces
    • Interop problems & business model problems: how to move around credentials
  • Meeting time change discussion - poll to be run soon
    • Consult with Asian working group specifically to gauge demand/interest in joining the interop call

💡 Identifiers & Discovery

🔓 DID Auth

  • SIOP special calls have been making a steady progress, Following are notable changes introduced to a SIOP v2 spec
  • Introduced DID Resolution method as part of RP Registration metadata section. When SIOP request is signed, RP’s client_id can be a DID and SIOP can obtain a key signing the request from RP’s DID Doc. The rest of the RP metadata must be obtained from a registration parameter in the SIOP request.
  • Introduced Dynamic SIOP Discovery metadata option. When RP has pre-obtained SIOP’s issuer identifier, it can use OpenID Connect Discovery to obtain SIOP’s metadata, namely authorication_endpoint. When Dynamic discovery is used iss in the ID Token in SIOP response must be a SIOP issued identifier and NOT self-issued.me/v2
  • OIDC4VP specification has been stable with minimum changes. Work on a spec how to issue VCs using OpenID Connect (which has an option to use Credential Manifest) is also happening, so stay tuned!
